Lot Essay

The reference 105.003 was produced between 1963 and 1969, and it was this reference that superseded all other brands by passing NASA’s rigorous qualification tests in 1965 that resulted in the OMEGA Speedmaster becoming the official watch used on space missions.

This reference is also the last of the Speedmasters with straight lugs, also known as the 'Pre-Professional'. In addition, it is sometimes referred to as the ‘Ed White’ after the first American astronaut to walk in space outside of the space module during the Gemini IV mission of 1965.

The present watch is an extremely early and attractive example of this landmark model. Known as the 'Asymmetric T', because there are two 'T' next to the “Swiss Made” on the dial at 6 o'clock, this reference 105.003-63 is a transitional version where the 'Ts' were added later, following legislation making the indication of radioactivity mandatory.

The Omega reference 105.003-63 'Asymmetrical T' is illustrated in Moonwatch Only, 60 Years of Omega Speedmaster by Grégoire Rossier & Anthony Marquié pp. 274.
